The Causes of Explosion Failure of Liquid Ammonia Cylinder

Abstract

Abstract Gas cylinders are widely used in industrial production and daily life. Due to the complexity of the medium contained in the cylinder and the unsafe factors in the use and management, cylinder accidents occur more frequently. This paper analyzes the cause of a burst accident in the liquid ammonia cylinder. The results show that the chemical composition and mechanical properties of cylinder materials basically meet the requirements of relevant standards. No obvious defects were found on the weld and fracture surface during NDT. The outer surface of the gas cylinder is severely corroded, especially in the weld area, where there is a lot of pitting corrosion.
